To all whom t may concern Be it known that we, NILs NrLsoN and LEONARD NILsoN, of -Wayzata, Hennepin county, Minnesota, have invented certain new and useful Improvements in Harvesters, of which the following is a specification.

rllhe primary object of' our invention is to provide a harvesting apparatus which can be easily and quickly attached to a traction engine and as readily removed therefrom, to the end that the engine may be used for operating the harvesting apparatus and for other purposes around the farm when the harvesting apparatus is removed. It will thus be unnecessary to provide a traction and operating means for the harvester independently of the means for operating the other farm implements.

A further object is to provide a connection between the traction engine and the harvesting apparatusl which will permit of the operation of the cutter-bar and carrier belts at a uniform, continuous speed while the traction wheel of the engine, operated from the same source of power, may be driven at a variable speed, thus permitting the operator to slow down the machine or increase its speed according to the character ofthe grain that is being cut -without altering the speed of operation of the harvesting device.

@ther objects of the invention will appear from the following detailed description.

v -The invention consists generally in various constructions and combinations, all as hereinafter described and particularly point- -ed out vin the claims.

, ln the accompanying drawings forming part of this specification, Figure 1 is a plan view of a harvesting machine embodying our invention, Fig. 2 is a rear view of the same, Fig. 3 is a side elevation, Fig. 4 is 1 detail view illustrating the driving connections between the traction wheel and the source of power, and the mechanism for driving the harvester reel.

ln the drawings7 2 represents the frame of the, machine, having a forward axlel 3 and forward. .wheels 4. The rear portion of the machine frame is supported,preferably, by a single traction wheel 5., mounted in bearings inxthe frame 2. i

having ash-aft 7 providedrwith la clutch and connected by a belt 8 with a shaft 9, extending lengthwise of said frame land connected through a shaft 10 with a crank disk tension of a spring 21; By the adjustmentA of the friction wheel the speed of the traction wheel driven throughthe friction disk may be increased or decreased, according to the character of the ground' over which the machine is moving or the grain in which the cutter-bar is operating.

Near the end of the drive shaft 15 is a transverse counter-shaft 2.2, ygeared at 23 to the drive shaft and driven therefrom. This shaft is provided with a clutch 2v2 near the drivers seat `23 to allow the operator of the engine -to stop or start the counter shaft and the mechanism connected therewith.

belt 24 extends backwardly from this countershaft and .drives a hubr 25 that is geared at 26 to a shaft 27, and'is mounted on a bracket '27. Thev shaft v27 has a sprocket wheel v28 meshing with a chain belt 29 which engages sprocket wheels.30, 31, 32 and A33 on the shafts f34, 35, 36 and 37. These shafts are journaledV in acarrier frame 38 that is mounted onthe upper portion of the yoke 39, the lower portion of which straddles the traction wheel 5 and is vertically adjustable by means of bolts 40 and holes 40 on the machine frame.' l(See Fig. 3.) This yoke has an oscillating movement on its pivots forward and backward and is operated by means of tilting bars 41;"connected to arms 42 on a rock shaft'43 that is operated by a lever 44.y The shafts 36 and "grain iselevated. These belts are common to all harvesting machines and we have not vthoivlght it necessary' to illustrate or describe them in detail'herein. The shaft 37 drives the binder mechanism which is also of common construction, and operates in substantially the same manner as in an ordinary harvester.

The frame 38 is rigid on the yoke 39 and tilts forward or backward therewith, and a traction engine is through the frame 38 and the yoke 39, so that when the yoke is tilted, both the frames 38. and 47 will be tilted. -The forward portion of the frame 47 supports the finger bar and the cutterbar, heretofore described, and the tilting of the frame 47 will impart a corresponding movement to said bars.

Above the cutter-bar is a reel 52 mounted on a shaft 53 that is journaled in bars 54 which bars are supported on the frame 38. The shaft 53 has a driving connection 5.5 .with a short shaft 56 that is geared at 57 to the forward end of the shaft 27. (See Figs.v 1 and 4.) This reel is capable of oscillation on its supports and is operated, preferably, by a lever 58, mounted on a hub 59 that is journaled on the shaft 43 and has an arm 60 connected with one of the bars 54 by a strap 61. Oscillation of the reel for- ,ward or backward is thus permitted to adjust it. in any preferred position with respect to the cutter-bar.

In the operation of the machine, the frame 38 and yoke 39 are mounted on the traction engine, the position of the yoke having been previously determined so that the cutterbar will be in alinement with the pitman for convenient adjustment thereto. The traction engine thus forms the operating mechanism for the harvester, the rear traction wheel performing its usual function for the engine, and the cutter-bar being positively driven from the source of power. p

We regard the location of the harvesting ymechanism with respect to the traction wheels as of particular importance, as .the weight of the elevator and the parts connected therewith is transferred directly through the vertically adjustable yoke to the axleof the traction wheel and materially increases the traction of the wheel and relieves the forward portion of the machine of its load, and therefore allows the steering wheels to be operated with greater facility.

The operation of the harvesting attachment when connected with the traction engine will be substantially the same as in an ordinary harvester. The weight of the frame 38 will be supported by the rear used for operating any other agricultural implement.

We claim as our invention 1. The combination, with a traction machine having forward carrying and guiding means and a rear traction wheel, of a harvesting mechanism having a raised portion at one' end straddling said traction wheel and pivotally supported by the axle of said wheel, said harvesting mechanism having a laterally extending part adjacent to the ground line provided with a carrying wheel, a cutter bar mounted in said laterally extending part and operatively connected with said traction machine, and means for tilting said harvesting mechanism forward or backward on its supports to raise or lower the teeth of said cutter bar.
